Homework Help Overview
The problem involves finding the velocity and acceleration of a particle moving along the x-axis, given its position function s(t) = 7t² + 33. The original poster expresses uncertainty about the correctness of their derivatives and whether the variable should be 'x' or 't'.
Discussion Character
- Conceptual clarification, Mathematical reasoning
Approaches and Questions Raised
- The original poster attempts to differentiate the position function to find velocity and acceleration, initially confusing the variable 't' with 'x'. Other participants clarify the correct use of 't' and confirm the derivatives.
Discussion Status
Participants are engaged in clarifying the differentiation process and correcting variable usage. Some have confirmed the derivatives as correct, while others inquire about the method used to obtain them, specifically referencing difference quotients.
Contextual Notes
There is a mention of confusion due to working on multiple problems with different variables, which may have influenced the original poster's notation.
